Shandong Jiangkai Metal Products Co., Ltd., known as JK Casting, supplies custom steel and iron castings from Gaomi, Shandong. Its two published casting routes are resin-coated sand and lost-wax investment casting, with in-house machining offered for the castings it supplies. The range centers on power-line fittings, oilfield cable-protector bodies and machinery housings, supports and replacement components.
What the published manufacturing scope means for a buyer.
JK Casting's offer is build-to-print supply rather than a stocked parts catalogue. A buyer can order raw castings for its own machining operation or add specified bores, faces, threads and other finished features to the same casting order. Carbon steel, ductile iron and grey iron are the regular material families; stainless and alloy-steel work requires a part-specific review. The website dates the manufacturing factory to 2002 and identifies Gaomi Changrong Precision Casting as its same-factory affiliate and the holder of the published steel-casting ISO certificate. The contracting entity, producing works and required document scope should be named together in the order. [1] [18]
Casting and finished interfaces can be quoted together or the casting can be delivered raw. This is useful when comparing the supplier's machining scope with an existing internal machining line: the comparison can include tooling, stock allowance, inspection and handling rather than only casting price. [5]
The power-line and oilfield pages show fitting and protector bodies with holes, hinge areas, saddles and locking interfaces. They provide a practical basis for discussing mating parts and machining, without treating a similar-looking photograph as proof of dimensions or rated performance. [7]
The machinery and OEM pages accept drawings, models, samples and worn-part evidence for replacement or second-source review. For an obsolete part, this opens a route to re-establish the required material and finished dimensions before a new casting and machining plan is approved. [8]
CNFX synthesis of the company’s published information.
The product groups below describe custom component work, not finished agricultural machines, construction equipment or complete electrical systems. Pins, fasteners and other mating hardware are separate scope items.
Clevises, shackles, clamp bodies, brackets and related overhead-line components are offered to controlled drawings or samples. Pin-hole position, opening, mating clearance and dimensions before/after galvanizing are key quotation inputs. State whether the order is for the cast body or an assembly with additional hardware. [6]
Published examples include ESP cable-protector and cross-coupling clamp bodies, plus drawing-based replacement castings. Define tubing and coupling envelopes, cable passage, body length, hinge-pin bores and locking features. Body manufacture and assembly-hardware supply should be priced separately where relevant. [7]
The range includes bearing-support and housing forms, flanged interfaces, bases, brackets and threaded bodies for equipment. Critical bores, shoulders, mounting faces, threads and their datums determine the machining and measurement plan. [8]
Agricultural examples include cast hubs, clamp brackets, seeder parts and linkage components. Construction enquiries cover housings, mounts, covers and replacement castings. These are component programmes: define the machine interface, wear or load conditions, seasonal demand and required material rather than assuming catalogue compatibility. [9]
Published processes, organized by production stage.
Provide the current drawing, cast grade and standard, quantities and whether the delivery is raw, partly machined or finished. For a sample-based replacement, identify unworn reference surfaces and the intended mating part rather than copying wear into the new dimensions. [5]
JK publishes resin-coated sand and lost-wax routes. Parting, cores, section changes, quantity and machining stock determine the proposal. Agree pattern ownership, sample checks and any tooling charges before release. [3]
Its machining page describes in-house turning, milling, boring, drilling and threading for supplied castings. Functional datums and clamping strategy connect the cast blank with the finished bores, faces and threads. Standalone machining of customer stock or third-party castings is explicitly outside the published scope. [4]
Define coating or heat-treatment requirements, no-coat surfaces, dimensional effects and acceptance records. Processing providers and specialist tests are agreed for the order; the catalogue of finishing options is not an inventory of owned coating or laboratory equipment. [12]
Link sample results and dimensional records to the drawing revision, material identity and shipment. Confirm changes, call-off quantities and packing protection before repeating the order. [15]
JK's published quality approach is drawing-led. The most useful acceptance package connects material, finished interfaces and agreed treatment to the specific part and production lot.
The published ISO 9001:2015 / GB/T 19001-2016 certificate names Gaomi Changrong Precision Casting Co., Ltd., which JK describes as its same-factory affiliate. The document covers processing of steel castings, number 78324Q0154R0S, issued 22 April 2024 with expiry 21 April 2027. It is not a certificate for every JK material or a complete power-line assembly; current surveillance and issuer status remain separate checks. [17]
Dimensional reporting, sampling, material traceability, heat treatment and any mechanical or non-destructive tests are defined before production. The site distinguishes specialist-test providers and report issuers, so a buyer can specify the required evidence without assuming all methods are available in-house. [13]
Galvanizing, plating or paint can affect a finished fit. The power-line and finishing pages emphasize which dimensions apply before treatment, which apply after it and which faces or bores are masked. Include those conditions in sample approval and final inspection. [6]
The reviewed pages provide component photographs and application groups, not named customer acceptance cases. Their value is in identifying the manufacturing and interface questions for a similar part.
Fitting bodies with pin and eye connections can be discussed as drawing-based batches. Load requirements, governing specifications, coating, markings and any project qualification belong with the component drawing; appearance alone does not establish utility approval. [6]
Protector bodies and clamp geometries are relevant where a buyer controls tubing, coupling and cable dimensions. Replacement enquiries need both the physical evidence and the intended finished fit, particularly when the only available sample is worn. [7]
Housings, hubs, bases and supports suit projects that combine cast geometry with a smaller set of accurately machined interfaces. Repeat programmes should identify initial quantity, annual call-offs, drawing revisions and corrosion-protective packing. [8]
CNFX procurement assessment.
JK Casting is relevant to buyers of custom steel or iron components who need casting and selected machining coordinated against a drawing. It is a more specific fit than a general-purpose CNC job shop: the stated machining service follows its own casting supply. Raw-casting purchasers, equipment OEMs and replacement-parts teams can use the same enquiry route while defining different finishing and documentation boundaries.
